What is the architecture of 8085?
The architecture of the 8085 microprocessor mainly includes the timing & control unit, Arithmetic and logic unit, decoder, instruction register, interrupt control, a register array, serial input/output control. The most important part of the microprocessor is the central processing unit.
What is micro processor architecture?
Architecture of Microprocessor The microprocessor is a single IC package in which several useful functions are integrated and fabricated on a single silicon semiconductor chip. Its architecture consists of a central processing unit, memory modules, a system bus, and an input/output unit.
What is a microprocessor explain its architecture with diagram?
The microprocessor is the CPU (Central Processing Unit) of a computer. It is the heart of the computer. Here, we will describe Intel 8085 as it is one of the most popular 8-bit microprocessor.
How many registers are there in 8085 and explain the general purpose register with diagram?
The 8085 has six general-purpose registers to store 8-bit data; these are identified as- B, C, D, E, H, and L.
What are the main features of 8085?
The features of 8085 include:
- It is an 8-bit microprocessor i.e. it can accept, process or provide 8-bit data.
- It operates on a single +5V power supply connected at Vcc.
- It operates on clock cycle with 50% duly cycle.
- It has on chip clock generator this internal clock generator requires tuned circuit like LC,
What is the importance of 8085?
It provides status, control and timing signals, which are required for the operation of memory and I/O devices. 8085 System Bus: Microprocessor communicates with memory and other devices (input and output) using three buses: Address Bus, Data Bus and Control Bus.
What are the types of processor architecture?
There are two primary processor architectures used in today’s environments: 32-bit (x86) and 64-bit (x86-64, IA64, and AMD64). These architectures differ in the datapath width, integer size, and memory address width that the processor is able to work with.
What is register in computer?
A processor register (CPU register) is one of a small set of data holding places that are part of the computer processor. A register may hold an instruction, a storage address, or any kind of data (such as a bit sequence or individual characters). Some instructions specify registers as part of the instruction.
What is register in microprocessor?
What are the types of microprocessor architecture?
There are three types of microprocessors namely, CISC, RISC, and EPIC.
What are the various register of 8085 explain in brief?
The 8085 has six general – purpose registers to store 8-bit data; these are identified as B, C, D, E, H and L as shown in the figure. They can be combined as register pairs – BC, DE, and HL – to perform some 16-bit operations.
What are special purpose registers in 8085?
In addition to the above general-purpose registers, the 8085 microprocessor has special-purpose registers, namely, Program Counter (PC), Stack Pointer (SP), Flags/Status Registers (SR), Instruction Register (IR), Memory Address Register (MAR), Temporary Register (TR), and Memory Buffer Register (MBR).
